DeLonghi Ecam 23.450S

Hello together,

Since the expert advisors in the shops unfortunately can't give me the right answers to my, much. stupid questions, I turn to you today, an objective forum.

My girlfriend and I (therefore mainly me) have been thinking for years about whether a fully automatic coffee machine should be used.
My girlfriend likes to drink milk mix drinks and I'm main. Coffee drinker (possibly a cappuccino). Furthermore, my girlfriend drinks a lot of tea.
About the question if she is profitable the spirits divide.

During the week I drink 1-2 coffees in the morning (at the moment capsule milk), my girlfriend tea or warm milk. At the weekend 3-4 coffees per day come together + visit etc.

At MM you can get the DeLonghi Ecam 23.450S for less than 650,- €. I like this machine optically very well and what I think is good is that the milk container is nice and tidy.
Technically it fulfills all the requirements of my layman, respectively I wanted to ask here if the following things work without problems and tasteless, without coffee aroma:

- hot water supply for tea? (Could the kettle be gone)
- Hot milk for cocoa or hot chocolate
- Coffee strength well adjustable (my girlfriend doesn't like strong coffee)?
- "pot quantity" well adjustable?

From my personal point of view such an investment isn't worth it with our coffee volume, but now that I have this "will-feel" I'm thinking more of an emotional purchase and the taste experience.

And I would like to have an opinion, or possibly another, price-similar, potentially better (???) device as a suggestion, if there is anything.

Many thanks for your time.
